You'll have to delete the AppleIntelHDGraphics* from the Installed HDD as well. Installing Chameleon might have overwrite some settings in your Extra folder. Try replacing that with the one in the Installer.

Sound like the patch above works to get you HDMI video, but not audio because you don't have a patched AppleHDA. Can you be specific of what Realtek card you have? Launch DPCIManager. Look under Audio Devices->Codec ID

I'm still reading up on it, but looks like it's missing the Country Code patch

Sleep will work with HD4000 (Optimus Enabled), but not HDMI as it's tied to the Nvidia card. Wern has gotten sleep to work on the E6420 with NVS4200M, perhaps he could assist with how it gotten it to work.

Try the updated patch here.

Was it working with 10.10.1? If so, what kext were you using?

Please upload your /Extra folder from Mavericks when it's working. Try booting with -v -f and post the error.

See here to get it to work in OS X. For Windows you just need the drivers from the vendor.

Did you install the FakePCIID? FakePCIID_BCM94352_as_BCM94360 or this FakePCIID_BCM94352Z_as_BCM94360CS2 depending on your card.

run this from the terminal and reboot. sudo perl -pi -e 's|\x41\x83\xFC\xFF\x74\x2C\x48|\x66\xC7\x06\x55\x53\xEB\2B|g' -i.bak /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents/MacOS/AirPortBrcm4360 sudo touch /S*/L*/E* sudo kextcache -Boot -U /

1) Sleep doesn't work with the Nvidia card - no solution so far. Use Caffeine.app to keep system from sleeping or you'll have to hard reboot 2) You need the new patch for 10.10.3 here . BCM94352 5 GHz/BT Handoff Patch (10.10 and newer) 1. Requires AirPortBrcm4360 WiFi Support and BT4LE 2. Patches 1. 10.10.3 and newer, 5GHz 1. Binary patch: AirPortBrcm4360 1. US/FCC the-darkvoid 1. Find: 41 83 FC FF 74 2C 48 2. Replace: 66 C7 06 55 53 EB 2B

I don't see it on the list, are you sure it has one?

Wern's DSDT has audio layout-id set to 0, you need it to be set to 12. Use MacIASL.app to open DSDT.aml, search for "layout-id" Change this "layout-id", Buffer (0x04) { 0x00, 0x00, 0x00, 0x00 }, to this "layout-id", Buffer (0x04) { 0x0C, 0x00, 0x00, 0x00 },

Sounds like you don't have a patched AppleHDA but only VoodooHDA for sound. There's not a lot of success for HDMI audio with VoodooHDA. What sound card do you have, perhaps there's a patched for it already.

Try this DSDT. Originally by the OP, but added the SD Card reader and other patches. and Install this to S/L/E DSDT.aml.zip

Quadro K1100M might not be supported, so you might have to use Intel HD 4600. HDMI output might not work either if it's attached to Nvidia and you're using HD 4600. Have a look at this guide. Be warned, he modded the BIOS, this could brick your system. System is similar but not exact model. This would be a start.

What CPU do you have? Chameleon or Clover? Try booting with -v -f and post the error. If Clover, hit space bar and select verbose mode.

Do you have a patched AppleHDA working or using VoodooHDA? Try this patch for HDMI video/audio sudo perl -pi -e 's|\x01\x05\x09\x00\x00\x04\x00\x00\x87\x00\x00\x00|\x01\x05\x12\x00\x00\x08\x00\x00\x87\x00\x00\x00|g' -i.bak /System/Library/Extensions/AppleIntelFramebufferAzul.kext/Contents/MacOS/AppleIntelFramebufferAzul

BCM4352z would be a good replacement if you want hand-off working

If you ran the patch from post #322, it made a backup call libCLVMIGILPlugin.dylib.bak. You just have to delete libCLVMIGILPlugin.dylib and rename libCLVMIGILPlugin.dylib.bak to libCLVMIGILPlugin.dylib from that directory. Don't forget to resign it when you're done. Else here's the file for 10.10.3 libCLVMIGILPlugin.dylib.zip

Sounds like the symptom where you HDD is shown as RAID (coreStorage) and will need to be revert to normal drive. See fix here.

Update for 10.10.3 : Found the fix. You'll need to restore AppleIntelHD5000Graphics, AppleSDXC (optional) , and libCLVMIGILPlugin.dylib to the vanilla if you have patched it previously. Install attached AppleIntelFramebufferAzul and FakePCIID to SLE. Replace DSDT to /Extra or /EFI/Clover/ACPI/Patched if you're on Clover. Reboot. HD4400_QE:CI.zip

The SMC-Version is correct for MBA 6.2. As for port-replicator, I don't have DP or DVI working either. Can only get mini DP and HDMI working from the laptop.

If you already have Mavericks installed, you can use the same bootpack for Yosemite. See my guide for Yosemite in my signature below. Post your files and I'll let you know what can be updated and/or leave out for Yosemite.

No, you don't combine them. You should have 2 separate files, a DSDT and an SSDT.
